Uh-oh! Juliette looks worried (again) on Grimm. NBC renews Grimm, Parenthood and more! When NBC's monster-filled crime drama moves to its new timeslot Tuesday at 10/9c, Juliette (Bitsie Tulloch) is struggling with the memories of Nick (David Giuntoli) that are slowly returning to her. What's a girl who's been scratched by a poisoned cat and suffering from selective amnesia to do? Go to reliable Monroe (Silas Weir Mitchell), of course! Check out this exclusive sneak peek below and see what special request Juliette has for our Blutbad friend: Poor Monroe! Why does he always get put in the middle? Meanwhile, Nick is investigating peculiar cow mutilations and reports of strange, glowing creatures. Both mysteries seem far easier to solve than his romantic troubles with Juliette. Grimm airs Tuesdays at 10/9c on NBC.
